(4) Programmable peripheral I/O area
Cautions 1. The programmable peripheral I/O area exists only in the CAN controller versions. This
area cannot be used with products that are not equipped with the CAN controller.
2. Only the programmable peripheral I/O area is seen as images of 256 MB each in the 4 GB
address space.
12 KB of addresses 03FEC000H to 03FEEFFFH are reserved as the programmable peripheral I/O area.

(5) External memory area
15 MB (00100000H to 00FFFFFFH) are allocated as the external memory area. For details, see CHAPTER 5
BUS CONTROL FUNCTION.
Caution
The V850ES/SG2 and V850ES/SG2-H have 22 address pins (A0 to A21), so the external
memory area appears as a repeated 4 MB image. When A20 and A21 pins are used, it is
necessary to set that EVDD = BVDD = VDD.
